Antibodies help protect monkeys from HIV-like virus, NIH scientists show
Date:5/5/2011

a modest protective effect, reducing the rate of HIV infection by 31 percent. The new research also provides an animal model to better understand the immune basis for vaccine protection against lentiviruses, a subclass of viruses that includes HIV and SIV. This knowledge will help guide strategies for the future development of AIDS vaccines.

The SIV vaccine regimen used in this study was similar to an HIV vaccine regimen currently being tested in humans in the NIAID-funded clinical trial known as HVTN 505. Both vaccine regimens consist of priming with a vaccine made from DNA that encodes immunodeficiency virus proteins, followed by boosting with an inactivated cold virus (adenovirus) that contains immunodeficiency virus proteins.
